1. The smart fridge will be
connected to the internet as part of a home network that runs your domestic
life, interacting with the barcodes on your food, and re-ordering them on-line
as you use them. Virtually all domestic appliances will be linked by computer,
so that the fridge can communicate with the cooker and rubbish bin, complex
tasks such as cooking a meal.

2. Children of the future will never
be able to complain that there's no one to play with. Equipped with virtual
reality headsets, they will be taking part in global games, for example, in
medieval jousting tournaments. Their opponents, selected by the computer, will
probably live on the other side of the world.

3. Cars of the future will take much
of the strain out of driving. The intelligent navigation system will be able to
choose the best route for you by monitoring an online traffic database for
hold-ups, while the cruise control keeps a constant distance from the car in
front. And if you exceed the speed limit, the speedometer will give a polite
warning to you.

4. Holographic conferencing and
virtual reality meetings will allow people to interact with colleagues and
clients via computer, without needing to leave the comfort of their own homes.
This will also mean that a lot more people will either work freelance from
home, or on flexible short-term contracts. The old concept 'jobs for life' will
be a thing of the past.

5. In the future it will become
harder to tell the difference between the human and the machine. All body parts
will be replaceable. A computer will function like the human brain with the
ability to recognize feelings and respond in a feeling way. We will then be able
to create a machine duplicate of ourselves and transfer our spirit so we will
be able to live for as long as we want.

6. There will be great changes to
the environment particularly because of the rising sea levels. Global warming
is expected to cause oceans to rise by one meter, which will increase the risk
of flooding. It will happen regardless of any future actions to curb greenhouse
gases. Projected climate change will also tend to degrade water quality through
higher water temperatures.

7. We will not rely so much on cash
as we do now. It will mainly be digital money, the inevitable medium of
exchange for an increasingly wired world. We will no longer need to carry a wad
of bills or fumble for exact change. Supermarkets will have iris recognition
systems so the money for our groceries will automatically be transferred from
our bank accounts as we're standing at the checkout.
